BUG: File read error.

[Harald H Hannelius]

I have a linux Slackware 3.X with kernel 2.0.35 and samba pre-alpha 2.0.0.
I have cvs'ed the latest code 1 Oct 98, 14:00 EET-DST.
I have gotten the pdc thing up with encrypted passwords, and domain
logins. When i map a share and try to access any file on any share I get
an error like 'Network access is denied' (NT4) or 'The device does not
exist on the network, reading drive H',' Abort,Retry,Fail', 'Failed on INT
24 - filename' (win98) if i try a 'type filename' on the client.

I have looked at the log.machinename, and discovered this:

This shurely looks like a bug to me, so I started to strace smbd, and came
up with this:

[pid 25682] stat("DPATH/sun", 0xbfffeba8) = -1 ENOENT (No such file or
director
y)

So, the smbd find the file 'sun', but when i request a read() it
segfaults. Why?

libc-5.4.44, gcc 2.7.2.3

Should I maybe try to compile the monster with egcs or something?

btw, what is DPATH? I'm not that good at C...
